I have been lurking this forum for a couple of seasons and am finally ready to make the switch to the BBB method. I purchased a Taylor K-2006C and discovered the CYA level to be high (150+) as I had suspected. Initial test results:
I have ordered 20 boxes of Borax (20 Mule) from Wal-mart and plan to add that when I get everything worked out with CYA. After several days of pumping down the water level and topping off with well water I have the following test results:
FC 3.4 (adding 2 gal 6% bleach today)
My question is regarding the TA. What caused the climb in TA? Should I deal with this prior to adding the Borax?
My long term plan is to bring CYA to 50, using liquid bleach (6 or 12% based on cost) and keep back flushing until CYA hits 30. This will allow me to return to using Tablets (Leisure Time 7oz Trichlor with 89% available Chlorine) as needed when I can't make liquid chlorine additions daily. I will keep an eye on CYA during the season and cease tablet use when I hit 50 ppm. Resume water changes until CYA hits 30 and repeat.
Any suggestions, concerns or comments?
